A Little Electromagnetic Humor

When Stefano Selleri submitted his paper that appears in this issue, he referred to it as a “short,

humoristic” piece. While the basic premise of evaluating the electromagnetic shielding eff ectiveness of medieval chain mail is certainly humorous, the analysis and results are of scientifi c interest. It turns out the chain mail can be modeled as a periodic surface, which has diff erent properties depending on whether it is assumed that the links are conductively isolated or connected. An analysis of the shielding eff ects was done over the frequency range from 100 MHz to 10 GHz. Having obtained these results, the author does have some fun applying them to possible use scenarios. It is my understanding that no knights were injured during this research....

On the Electromagnetic Shielding Eff ectiveness of Chain-Mail Armor

Stefano Selleri

Department of Information EngineeringUniversity of Florence

Florence, ItalyE-mail: Stefano.selleri@unifi .it

Chain-mail armor was a type of body protection that dates back to the fourth century BC. It was used extensively in times of war up to the advent of fi rearms. It had a limited use later on, but was still reported as being worn up to the 20th century.

The modern uses of chain mail are mostly civilian, such as protection for butchers, shark protection for divers, and, notably, for historical reenactment and live-action role-playing games. In these latter cases, there is no need that the chain mail really be weapon proof, and it is usually made of aluminum to reduce weight.

It is legitimate to ask ourselves if chain mail could be used as a wearable shield against electromagnetic radiation.

1. Electromagnetic Analysis Approach

Chain mail (Figure 1) is composed of interlocking rings. In the most common form, these are woven so that each ring is connected with four others (Figure 2). The rings are, of course, opened to allow weaving. They may be soldered or riveted for superior strength, or they may just have their ends juxtaposed.

The rings are usually quite small, usually between

3/8 in to 1/2 in (9.5 mm to 1.3 mm) diameter. This makes creating chain mail a long and tedious task, yet this also makes a planar chain-mail sheet a periodic surface. Under the

realistic hypothesis that such a sheet of mail is illuminated by an electromagnetic source far enough away in space so that the electromagnetic fi eld can be assumed to have a plane-wave structure, the problem can be analyzed on a single periodic cell with appropriate periodicity boundary conditions (Figure 3 and [1]).

A simplifi ed electromagnetic model is sketched in Figure 3. For completeness, two models were considered. The fi rst was an “isolated” model, in which no electrical connection was present between rings, hence eff ectively simulating passivated or painted surfaces, allowing for capacitive coupling but not for current fl ow. The second

was a “connected” model, in which the rings were touching, hence simulating electrical connection between rings and hence the possibility of current fl ow among them. In both cases, the rings were modeled as a toroid with a radius of revolution of 6 mm (0.23622 in) and a revolving section that was a circle. For the “isolated” case, the radius of the revolving section was 0.75 mm (29.52 mils), while for the “connected” case, the radius was 1 mm (39.37 mils) (Figure 3).

2. Numerical Results

The problem was hence reduced to that of a periodic cell illuminated by a plane wave, and was numerically solved. The results were given in terms of the transmitted intensity ratio and the refl ected intensity ratio, in dB, for both connected and unconnected rings, over a 100 MHz to 10 GHz band (Figure 4). In the fi gure, the band from 300 MHz to 6000 MHz is highlighted, since it holds most mobile phone standards up to 3G and 4G, going up from 300 MHz to 2600 MHz [2, 3], as well as Wi-Fi, which, as described in IEEE Standard 802.11, covers the 2.4 GHz to 5.9 GHz band [4].

It was apparent from Figure 5 that for the lower part of the spectrum, the chain mail guaranteed at least 20 dB attenuation in the transmission up to 3 GHz, and that the connected mail gave about an extra 5 dB of protection. This was expected, since in the connected mail, current paths could freely cross rings, and not only through parasitic capacitances. In any case, resonances in the mail arose where the ring circumference (about 2 cm) started to be comparable with a wavelength. Indeed, resonances appeared at lower frequencies with respect to a single isolated ring, due to the reactive load of the neighboring rings, causing a signifi cant reduction of shielding eff ectiveness at the top of the Wi-Fi band.

The Radio Science Bulletin No 367 (December 2018) 11

The shielding level (a few tens of dB) was much lower than that of a solid aluminum shield, the eff ectiveness of which may exceed 100 dB at these frequencies. A solid aluminum or other metal shielding can be provided by full-plate mail, which, unfortunately, is much less comfortable to wear.

3. Clinical Data

Although for ethical reasons it was inappropriate to have volunteers walk around in full chain mail all day long while using their mobile phones or surfi ng the Internet via Wi-Fi, some indirect proof of benefi cial eff ects on health could be inferred from statistical data on mortality collected when chain mail was fashionable.

By browsing historical references, we have evidence of a large number of deaths during the Crusades (1095-1291) among people wearing various kinds of armor, typically chain mail [5]. However, deaths other than due to old age were credited to pestilences, battle, injuries, or starvation. The author could not fi nd in the records a single case reporting brain cancer, or any other cancer, for that matter [6].

4. Conclusions

Wearing chain mail significantly lowers electromagnetic radiation absorbed by your brain or body. It is anyway advisable to keep the phone outside the coif when talking. Otherwise, radiation would occur within the shield, which would act as a low-Q-factor resonant cavity. That would enhance rather than diminish the eff ects of the radiation.

Science, Faith and Openness in the Workplace

Krishnasamy T. Selvan

Department of Elect ronics and Communication Engineering

SSN College of EngineeringKalavakkam 603110, India

E-mail: selvankt@ssn.edu.in

A rational thought system is defi ned to be based on “reason and logic, rather than emotion” [1]. Science

is generally thought to be such a rational system, as opposed to, for example, religion, which is considered essentially a matter of faith. The implication is that the results obtained in the pursuit of science are objective, and there is no place for faith in accepting them as true.

However, in practice, faith appears to be a factor in the pursuit of science, as well. When a scientifi c body reports certain fi ndings, there is a general expectation that the objectivity of those fi ndings be taken for granted by those outside of the corresponding specialty and by the common public. It is natural that except for those involved in the research, others would either not have access to or not be able to understand the complex processes and methods involved. Now as is generally expected, if these other persons should take the fi ndings for granted, it would be possible only if they choose to believe – or place faith – in the researchers and processes. Faith is thus inherent in science, as well.

One can argue that science has produced several success stories, and therefore its claim to objectivity can be considered a fact. However, as Karl Popper, one of the greatest philosophers of science of the twentieth century, said [2], “science often errs” as well. Even in respect of basic sciences, according to him [3], “...all knowledge is provisional, conjectural, hypothetical – we can never fi nally prove our scientifi c theories, we can merely (provisionally) confi rm or (conclusively) refute them”.

Given the above, if one can place faith in what are called scientifi c fi ndings, it logically follows that one can also choose to place faith in, say, what a religious scripture says. Where one places faith is one’s choice, and can be conditioned or necessitated by his or her exposure, knowledge, and other factors.

Scientifi c and religious faiths can and often do exist together, as evidenced by the lives of many well-known scientists. For example, Werner Heisenberg, one of the founding fathers of quantum physics, said [4]:

The Radio Science Bulletin No 367 (December 2018) 15

It has repeatedly been claimed that scientifi c truth can-not be reconciled with the religious interpretation of the world. Although I am now convinced that scientifi c truth is unassailable in its own fi eld, I have never found it possible to dismiss the content of religious thinking as simply part of an outmoded phase in the consciousness of mankind, a part we shall have to give up from now on. Thus in the course of my life I have repeatedly been compelled to ponder on the relationship of these two regions of thought, for I have never been able to doubt the reality of that to which they point.

To Michael Faraday, one of the greatest experimental scientists of the nineteenth century, in the words of his fi rst biographer, Bence Jones [5],

...his religion was a living root of fresh humility, and from fi rst to last it may be seen growing with his fame and reaching its height with his glory, and making him to the end of his life certainly the humblest, whilst he was also the most energetic, the truest, and the kindest of experimental philosophers.

Although wars have been fought over religion, technology, an off shoot of science, has played a signifi cant role in them in recent times. Of course, this is no reason for being critical of either religion or science.

How then can we address the growing intolerance in society? It is possible by noting that any system of thought conceived by man, being always based on limited experiences and observations, gives scope for inevitable variety in views and perspectives. Thus perhaps “no thought systems conceived or conceivable by humans can be fl awless and perfect,” [6] and hence a true rational idea could be to entertain faith on one or several thought systems such as science, religion, or atheism, but never to be dogmatic about it, so that we never harm another living being in the name of that faith.

With specifi c reference to our professional sphere, such an attitude can signifi cantly help one to be more open and less judgmental in the workplace. Besides reducing stress for the individual, this can also facilitate establishing a “deep connection to, or relationship with” colleagues, which is a “critical dimension of workplace spirituality” [7].

1. Introduction

Arrays are fundamental structures in all areas of electromagnetics and they are natural components

of antenna systems, microwave components, and optical devices. Unsurprisingly, numerous electromagnetic analysis and solution techniques have been developed in the literature for arrays, leading to many implementations with diverse capabilities, e.g., from “instant” but approximate array-factor approaches, to time-consuming but accurate full-wave solutions. The suitability of a solver naturally depends on the array (e.g., array elements, positioning of elements, periodicity, electrical sizes, material properties), the existence of other structures (e.g., a platform on which the array is mounted, an object to be detected in radar scenarios, a human body that interacts with the array), as well as the required accuracy and preciseness of numerical solutions. Even an infi nite model may perfectly work in some applications, while extremely sophisticated and elaborate techniques may be needed to analyze an array used in critical scenarios.

In SOLBOX-14, a relatively simple but still challenging set of problems involving arrays of strips are considered. Accurate solutions of the presented problems involve several challenges:

• They involve large numbers of elements (i.e., 7569 and 16,200).

• They are fi nite but electrically large (i.e., 20 , where is the wavelength).

• They are excited by nearby sources, i.e., dipoles located above them, so that array elements are excited quite nonuniformly.

Sample solutions, which are also presented in this issue, were obtained via a relatively direct approach using a full-wave electromagnetic solver, while the contributors believe that more-effi cient and/or accurate solutions should be achieved by using alternative approaches. Please do not hesitate to send and share your solutions for SOLBOX-14, as well as for the previous problems defi ned in SOLBOX-01 to SOLBOX-13, in this column.

2. Problems

2.1 Problem SOLBOX-14

(by Sinan Emre Senem, Sena Alkış,and Özgür Ergül)

Problem SOLBOX-14 involves two diff erent arrays of metallic strips that are located on the x-y plane. Each strip has a length of 1.5 mm and a width of 0.2 mm, while their positioning with respect to each other was taken from [1]. Using the perfect-conduction assumption, the thicknesses of the strips can be assumed to be zero; however, they may also have nonzero thicknesses. As shown in Figure 1, the fi rst array is an arrangement of 7569 strips in a diamond shape. The overall size of the array is 195.0 mm × 129.2 mm. The second array, shown in Figure 2, is an arrangement of 180 × 90 strips, leading to a structure with a size of 202.9 mm × 134.4 mm. Each array is excited by a small

time-harmonic source, which can be modeled as a Hertzian dipole, located close to the strips. In the sample results, the Hertzian dipoles were assumed to be located symmetrically at a distance 4 or above the arrays, where is the wavelength at the selected operating frequency of 35 GHz. The arrays were expected to be simulated above 20 GHz, i.e., at the frequency ranges that have recently attracted great interest in the context of 5G applications. As to the simulation results, the near-zone or far-zone radiation characteristics, e.g., electric-fi eld intensity distributions with respect to position, can be presented.

3.2 Short Description of the Numerical Solutions

The array problems described in SOLBOX-14 were formulated by using the electric-fi eld integral equation in the frequency domain and solved by using the Multilevel Fast Multipole Algorithm (MLFMA) [2]. The frequency was set to 35 GHz, and the strips were assumed to be perfectly conducting. At this frequency, the size of the diamond-shaped array was approximately 22.8 15.1 , while the rectangular array had dimensions of 23.7 15.7 . A standard set of the Rao-Wilton-Glisson functions was used to expand the electric-current density induced on the strips. Using four triangles per strip for modeling, 30,276 and 64,800 triangles were used for the diamond-shaped and the rectangular arrays, respectively. As also mentioned in the problem defi nition, the excitations were modeled as Hertzian dipoles. The Generalized Minimal Residual (GMRES) algorithm was used for iterations, while the iterative convergence criteria was set to 0.001 in all solutions.

3.3 Results

Figures 3 and 4 present the results when the diamond-shaped array was excited by an x-directed Hertzian dipole with unit dipole moment located at 4 or above the array. For comparison, a perfectly conducting zero-thickness patch with the same dimensions was considered. Figure 3 includes the amplitude of the near-zone total electric-fi eld intensity (in dBV/m) in the vicinity of the array/patch sampled on the z-x and z-y planes. The patch acted as a good refl ector with vanishing fi eld values below it, while the overall radiation in the z direction was enhanced. A single beam was observed when the dipole was 4 above the patch. However, when the distance was enlarged multiple beams were generated, as expected. On the other hand, as somewhat predicted, the array behaved quite diff erently. On the z-x plane, the structure seemed to be transparent so that the radiation of the dipole was slightly deformed. A good transmission across the array was also observed on the z-y plane, while the asymmetry was signifi cant. In particular, when the dipole was at away from the array, good radiation was observed in the z direction (as opposed to the divided radiation of the patch case), in addition to two beams that were caused by refl ections. In general, the array provided interesting radiation characteristics that superposed full-patch and no-patch (Hertzian dipole in free space) properties. Bistatic far-zone electric-fi eld intensity graphs, shown in Figure 4, further demonstrated the interesting response of the array in comparison to the

patch. For both cases (Hertzian dipoles at 4 and )the overall radiation was maintained in the z and z directions, as well as at off -axis directions on the z-y plane with many peaks and dips.

Figures 5 and 6 include results for the rectangular array, again in comparison to a patch of the same size (202.9 mm × 134.4 mm). Only one type of excitation involving an x-directed Hertzian dipole at was considered. The results were similar to those for the diamond-shaped array and the corresponding patch. On the z-y plane, the oscillatory nature of the radiation of the array with almost similar levels in the z and z directions is remarkable. The peaks occur at 70° and 290°, while strong dips were at 85° and 275°. Figure 7 further shows the sensitivity of the radiation characteristics of the rectangular array to the thickness of the strips used. Specifi cally, instead of assuming zero thickness, we also considered strips with 0.05 mm and 0.1 mm thicknesses. It could be observed that the major radiation characteristics did not change. However, the peaks and dips on the z-y plane become stronger as the thickness was introduced.

When asked to write this article, I thought whatever will I write? As a child, I did not have long-term

goals of being a scientist. My goals were more immediate: get good grades, fi nish homework early to be able to go out to play, and generally have fun. My family was close – perhaps a little too close, as I grew up in a three-family home, with my grandparents on the fi rst fl oor; my aunt, uncle, and cousins on the third fl oor; and my family sandwiched in the middle, on the second fl oor. My immediate family included my parents and my two brothers. Together with my brothers and cousins, we walked to the neighborhood Polish Catholic School; we worshipped at the neighborhood Polish church; and we played within a four-block radius of our home, in an ethnic part of Boston. Although Boston was a big city, we lived in a very small part of it: a very nice small part, by my recollection, but quite limited in its view of the world.

This time I present Patricia Doherty, Director at the Institute for Scientifi c Research at Boston College, Massachusetts. Pat is the only female Commission Chair of the ten Commissions of URSI. Pat’s Commission G comprises Ionospheric Radio and Propagation, in line with her interests in space weather and global navigation satellite systems with applications.

Pat’s story is similar to those of several other female scientists of her generation. Due to talent in mathematics and technology, she chose at that time what was still an unusual career way for a woman. She did not continue directly in scientifi c research, and stayed a few years at home with kids. This prepared her well to go over to space research and make a wonderful career there. Here comes her story

Oh the Places You Will Go…

Ours was largely a blue-collar family, and it was my generation that was deemed to be the fi rst college graduates in the family. At the time, it seemed to be a heavy expectation, starting with whatever will I be? The common goals among girls I knew at that time included becoming teachers, nurses, and secretaries. All noble careers, for sure, but nothing that interested me. It wasn’t until I was at the University of Massachusetts that I appreciated a strong aptitude for mathematics and statistics, and an interest in physical science. Here is where I started my career: not as a scientist, but as a statistician for the insurance industry, and later for the US Internal Revenue Service. This path seemed like a good idea at the time, and it broadened my view of the world just a little bit more – but still generally limited to New England.

The Radio Science Bulletin No 367 (December 2018) 23

Just a few years into my professional career, I married a wonderful man (also from Boston). We soon had a daughter, and then a son. With this young family, I felt that I was needed more at home, and decided to take eight years out of the workforce. Those were memorable years, and I enjoyed them immensely. It did put a gap in my career, but it also gave me more time to think about the future, as I was sure that I wanted to professionally follow a diff erent path.

Around the time I decided to resume my career, I had a fantastic opportunity to join a research group at Emmanuel College. This came about quite unexpectedly, through a friend who knew my interests and technically capability. As it happens, she also knew the Director of the Emmanuel College Space Science group, and thought we would be a good match. I am forever grateful to this person, as it was a turning point in my career. The Emmanuel College group supported US Air Force scientists in their studies of the Earth’s ionosphere and radio propagation. Although this was somewhat of a foreign topic for me, it certainly peaked my interest, and I made it my ambition to learn as much as possible on the topic.

Another lucky occurrence for me was that I had the unparalleled opportunity to work with leaders in our fi eld, including Mr. Jack Klobuchar and Drs. Santimay and Sunanda Basu. They were quite patient with me as I learned as much as possible from them and furthered my studies. As you can see, my world was getting larger by this time, as I also had opportunities to work with radio scientists and engineers from around the world when they visited our laboratories in the Boston area.

A couple of years later, I moved to the Institute for Scientifi c Research at Boston College to expand my adventures in space research. It was at Boston College that

my career really started to take shape. After several more years of study and research, I developed competence as a radio scientist, with a focus on studying the ionosphere using satellite signals of opportunity, and later with the Global Positioning System (GPS) satellites. I was also researching space weather, and its eff ects on GPS and GPS-based applications, such as the US Federal Aviation Administration’s Wide Area Augmentation System (WAAS), a civil aviation system that would be largely dependent on GPS satellites. At Boston College, I continued to advance my career from Research Scientist to Senior Research Scientist, Principal Investigator, and fi nally as the Director for the Institute for Scientifi c Research (ISR) at Boston College. ISR is an organized research institute, supporting the research mission of Boston College to conduct national and international signifi cant research that advances insight and understanding, enriches culture, and addresses pressing social needs. With this mission, I felt most at home in my career of choice – or, more appropriately, my career of happenstance. It was certainly not something I planned, but something that has been most rewarding and enjoyable. It has given me extraordinary opportunities to observe the scientifi c exploits of our highly skilled team

of scientists in the fi elds of space physics, space chemistry, solar-terrestrial research, space weather, and astrophysical studies. It has further expanded my view of the world, with many chances to work and make friends from around the globe.

One of the highlights of my career has been an outreach program that has played a role in the expansion of space science education and research in developing countries (Figure 1). This program has been performed under a partnership between Boston College and the Abdus Salam International Centre for Theoretical Physics (ICTP) to host a series of workshops on the use of Global Navigation Satellite Systems (GNSS) for applications with societal benefi ts and for space science research. Since 2009, annual workshops have hosted approximately 50 participants from developing countries in Africa, Asia, Eastern Europe, and South America. These workshops have increased the number of young scientists studying space science in developing nations, and have dramatically increased the publication rate of scientists from these countries. In addition, we have worked to increase the number of women participating in our workshops. Our fi rst workshop included just a few female participants from Nigeria, Kenya, and Egypt. However, over the years we have steadily increased the number of women participants (Figures 2 and 3). This success was particularly evident in our 2018 workshop, where we had participation from 29 countries, and 49% of those participants were women. This, together with many other international experiences, have certainly expanded my view of the world: from a small and sheltered beginning to having so many colleagues and friends from around the world.

I am humbled to note that along the way, I have been blessed by much recognition in the world of radio science. This has ranged from serving as the 2013-2015 President of the Institute of Navigation (ION) and as the current Chair of URSI Commission G, to being awarded fellowships in ION, the African Geophysical Society (AGS), and URSI. Finally, I am a recent recipient of the 2017 GPS World Leadership Services Award and the 2018 American Geophysical Union (AGU) Space Physics and Aeronomy Richard Carrington (SPARC) Education and Public Outreach Award.

I have many people to thank for the enjoyment of my career. I have had much support from supervisors, sponsors and colleagues, both male and female. We often hear stories where women felt they had been held back in their career due to male dominance in the workplace. I can honestly state that this has not been my personal experience. Both men and women alike have done much to support me along the way. I particularly thank my mentors, including Jack Klobuchar, Santimay Basu, and Sunanda Basu; and my colleagues, including everyone at Boston College’s ISR and so many others in the US and beyond. I would like to note a special thanks to Dr. Reinhart Leitinger and

Jack Klobuchar, who sparked my interest in URSI; to Dr. Sunanda Basu, for encouraging me to lead a scientifi c organization; to Dr. P.V.S. Rama Rao (now deceased), who supported all of my eff orts in leadership of the URSI Commission G and its Beacon Satellite Study group; and especially to Prof. Sandro Radicella, who inspired me to reach out to the developing world. Together with Sandro and his team at ICTP, our organizations have performed 10 outreach workshops that have been as enjoyable as they were eff ective. Finally, I thank my husband, Charlie, my children, Karen and Brian, and my three beautiful grandchildren, Hailey, Liam, and Julia. Without their love and support, nothing here could have happened.

When looking back on my career, the book Oh, the Places You’ll Go by Dr. Seuss comes to mind. After growing up in a very small and somewhat sheltered part of Boston, I have had paramount opportunities to perform space research, to work with a stellar group of national and international scientists, and to travel to distant places on the globe.

Now that I have been in this career for many years, I feel that I can off er some advice to young women entering this fi eld: that is to have confi dence in yourself to do what you may think is not possible; to not be afraid to make a mistake (everyone make mistakes); to respect your colleagues (even when they make mistakes); to reach out to other women (and men) for friendship and to provide reassurance and encouragement they may need to succeed; and, fi nally, to be patient, fl exible and understanding when it comes to balancing work and family for yourself and for your colleagues and staff . You really can have it all!

“Today is your day. You’re off to Great Places! You’re off and away!”

The Radio Science Bulletin No 367 (December 2018) 57

Information for Authors

Content

The Radio Science Bulletin is published four times per year by the Radio Science Press on behalf of URSI, the International Union of Radio Science. The content of the Bulletin falls into three categories: peer-reviewed scientifi c papers, correspondence items (short technical notes, letters to the editor, reports on meetings, and reviews), and general and administrative information issued by the URSI Secretariat. Scientifi c papers may be invited (such as papers in the Reviews of Radio Science series, from the Commissions of URSI) or contributed. Papers may include original contributions, but should preferably also be of a suffi ciently tutorial or review nature to be of interest to a wide range of radio scientists. The Radio Science Bulletin is indexed and abstracted by INSPEC.

Scientific papers are subjected to peer review. The content should be original and should not duplicate information or material that has been previously published (if use is made of previously published material, this must be identifi ed to the Editor at the time of submission). Submission of a manuscript constitutes an implicit statement by the author(s) that it has not been submitted, accepted for publication, published, or copyrighted elsewhere, unless stated diff erently by the author(s) at time of submission. Accepted material will not be returned unless requested by the author(s) at time of submission.

Submissions

Material submitted for publication in the scientifi c section of the Bulletin should be addressed to the Editor, whereas administrative material is handled directly with the Secretariat. Submission in electronic format according to the instructions below is preferred. There are typically no page charges for contributions following the guidelines. No free reprints are provided.

Style and Format

There are no set limits on the length of papers, but they typically range from three to 15 published pages including fi gures. The offi cial languages of URSI are French and English: contributions in either language are acceptable. No specifi c style for the manuscript is required as the fi nal layout of the material is done by the URSI Secretariat. Manuscripts should generally be prepared in one column for printing on one side of the paper, with as little use of automatic formatting features of word processors as possible. A complete style guide for the Reviews of Radio Science can be downloaded from http://www.ips.gov.au/IPSHosted/NCRS/reviews/. The style instructions in this can be followed for all other Bulletin contributions, as well. The name, affi liation, address, telephone and fax numbers, and e-mail address for all authors must be included with

All papers accepted for publication are subject to editing to provide uniformity of style and clarity of language. The publication schedule does not usually permit providing galleys to the author.

Figure captions should be on a separate page in proper style; see the above guide or any issue for examples. All lettering on fi gures must be of suffi cient size to be at least 9 pt in size after reduction to column width. Each illustration should be identifi ed on the back or at the bottom of the sheet with the fi gure number and name of author(s). If possible, the fi gures should also be provided in electronic format. TIF is preferred, although other formats are possible as well: please contact the Editor. Electronic versions of fi gures must be of suffi cient resolution to permit good quality in print. As a rough guideline, when sized to column width, line art should have a minimum resolution of 300 dpi; color photographs should have a minimum resolution of 150 dpi with a color depth of 24 bits. 72 dpi images intended for the Web are generally not acceptable. Contact the Editor for further information.

Electronic Submission

A version of Microsoft Word is the preferred format for submissions. Submissions in versions of TEX can be accepted in some circumstances: please contact the Editor before submitting. A paper copy of all electronic submissions must be mailed to the Editor, including originals of all fi gures. Please do not include fi gures in the same fi le as the text of a contribution. Electronic fi les can be send to the Editor in three ways: (1) By sending a fl oppy diskette or CD-R; (2) By attachment to an e-mail message to the Editor (the maximum size for attachments after MIME encoding is about 7 MB); (3) By e-mailing the Editor instructions for downloading the material from an ftp site.

Review Process

The review process usually requires about three months. Authors may be asked to modify the manuscript if it is not accepted in its original form. The elapsed time between receipt of a manuscript and publication is usually less than twelve months.

Copyright

Submission of a contribution to the Radio Science Bulletin will be interpreted as assignment and release of copyright and any and all other rights to the Radio Science Press, acting as agent and trustee for URSI. Submission for publication implicitly indicates the author(s) agreement with such assignment, and certifi cation that publication will not violate any other copyrights or other rights associated with the submitted material.
